Project Migration Task: Python/FastAPI to Bun/Hono

1. Role & Objective

Act as a Senior Backend Engineer expert in both Python (FastAPI) and the modern JavaScript/TypeScript ecosystem (Bun runtime).

Your Goal: Rewrite the existing API service located in the python-ref/ directory using Bun, Hono, and SQLite.

The source code is located in the python-ref/ folder. It currently runs on:

You must use the following stack for the rewrite:

Runtime: Bun (latest version)
Framework: Hono (latest version)
Database: Native bun:sqlite (do not use generic node-sqlite3 unless necessary, prefer Bun's native high-performance driver).
Language: TypeScript

The new service must be a "drop-in" replacement. Adhere to the following rules strictly:

Analyze the SQL schemas or ORM models in python-ref.
Recreate the exact same database table structures (table names, column names, data types, constraints).
If the Python code uses an ORM (like SQLAlchemy or Tortoise), translate the logic to raw SQL or a lightweight query builder suitable for bun:sqlite.

Keep all API URL paths exactly the same (e.g., if Python has /api/v1/users, Hono must have /api/v1/users).
Keep HTTP Methods exactly the same (GET, POST, PUT, DELETE).
Keep Request/Response JSON formats exactly the same. Field names must not change (e.g., do not change user_id to userId in the JSON response, keep it consistent with the old API).

Organize the code logically (e.g., separate db.ts for database connections, index.ts for routes).
Use TypeScript interfaces to define the shape of Request/Response bodies.

Please read the files in python-ref/ recursively. Then, generate the following:

Project Setup: The package.json command or content needed to install dependencies.
Database Setup: A script or function to initialize the SQLite database matching the old schema.
Application Code: The full source code for the Hono application.

Start by analyzing the key files in python-ref/ and summarizing the endpoints and schema you found, then proceed to write the code.
